  • the invention relates to a profile strip of a vehicle body, which is designed with at least one shell component made of fiber-reinforced plastic, in which the profile strip is loaded in a bending direction to bending and the pultrusion component is arranged in the bending direction next to the shell component, and wherein the pultrusion member with an outer shell and at least one inside web coupled thereto inner web is designed.
  • a similar profile strip is known from DE 10 2010 012 715 A1.
  • the invention further relates to a use of such a profile bar on a vehicle body.
  • a profile strip of a vehicle body wherein the profile strip is designed with at least one shell component of fiber reinforced plastic and at least one Pultrusionsbauteil in which the profile strip is loaded in a bending direction to bending and the pultrusion component is arranged in the bending direction next to the shell component, and in the the pultrusion component is designed with an outer shell and at least one inside web coupled thereto.
  • the profile strip extends the at least one inner web in the bending direction and the at least one shell component has additional inner ribs, which also extend in the bending direction.
  • Under shell component of fiber reinforced plastic is a component to understand that is made of at least one shell of plastic as a matrix, in particular synthetic resin in the form of polyester resin or epoxy resin, and embedded therein reinforcing materials or reinforcing fibers.
  • Both thermoset and thermoplastic polymers can be used as the matrix.
  • thermosetting matrix systems the relatively inexpensive polyester resins, vinyl ester resins and epoxy resins are used. It is also possible to produce thermoplastic fiber composites.
  • the matrix systems used are then predominantly polyamides, polypropylenes and polyethylenes.
  • the reinforcing material used are predominantly synthetic fibers of glass, carbon and aramid, which can be used as rovings, scrims, fabrics or nonwovens.
  • a pultrusion component is to be understood as meaning a component which has been produced by means of a pultrusion process. Pultrusion processes are also referred to as extrusion processes.
  • a pultrusion plant comprises a fiber shelf, fiber guides, an impregnator, forming or hardening tool, a puller, and a lengther unit. In the pultrusion process, the fiber rovings are guided via fiber guides from a multi-storey bobbin trimmer into the resin bath, the impregnation device. The fibers pass through several preform stations, so that they are brought to the desired profile shape.
  • Mats, fabrics, scrims or nonwovens may be incorporated into the process at the fiber guides to adapt / optimize the mechanical properties over that of purely unidirectional reinforcement as achieved by fibers.
  • bath process the reinforcing fibers are introduced from above and drawn through an open resin bath in which the fibers are deflected by pinholes. This method is the most common for producing pufrudierter profiles, especially with simple cross-sections.
  • the impregnation and impregnation takes place in an open resin bath through which the dry fibers are drawn.
  • the deflection of the fibers into and out of the resin bath takes place through guide diaphragms,
  • the pull-through method is used in particular in the production of profiles with geometrically complex cross-sections.
  • the reinforcing fibers are passed without deflection through the resin bath, so that the impregnating unit is passed through horizontally.
  • At the inlet and outlet side of the resin bath are preform stations, which are similar to the later profile form.
  • the matrix swept through the fiber guides is collected under the impregnating unit with the aid of a pan.
  • the reinforcing fibers are guided without deflection by the impregnating tool.
  • This tool has the shape of the profile to be produced and expands inside.
  • the resin is injected from both sides transversely to the fiber direction. This method is particularly preferred in the present case
  • a final shaping of the manufactured profiled strip and / or a hot curing at temperatures between 100 ° C. to 200 ° C. is preferred according to the invention.
  • the finished profile strip is continuously conveyed by a subsequent drawing device, eg, in the form of a caterpillar take-off or by pneumatic grippers, and pulled out of the tool at a constant speed (hence the English name Pultrusion from "pull") and "extrusion "- Pressing).
  • a subsequent drawing device eg, in the form of a caterpillar take-off or by pneumatic grippers
  • a process speed of 0.1 m / min to 1.2 m / min is preferred.
  • Also preferred according to the invention is the so-called radius pultrusion.
  • the mold whose cavity corresponds to the course of the desired profile, is moved stepwise over the resulting profile.
  • the gripper which is simply present in this process, retains the profile during the forward movement of the mold and releases the resulting profile during the backward movement of the mold, as shown in the diagram of the process of radius pultrusion.
  • the profile strip is loaded on the associated vehicle body in a bending direction on bending and the pultrusion component is then arranged in the bending direction next to the shell component.
  • the pultrusion component is further designed with an outer shell and at least one inner web coupled thereto inside, wherein the at least one inner web extends in the bending direction.
  • the shell component and / or the pultrusion component may, in particular, optionally also be filled with foam.
  • the filling with foam is particularly advantageous after the production of the components in a separate manufacturing step.
  • the pultrusion component can be glued flat with the shell component.
  • Such surface bonding couples the two components to one another in such a way that a composite component is created which has correspondingly high strength values.
  • the invention is furthermore directed specifically to a use of such a profile strip according to the invention on a passenger line of a vehicle body.
  • a sill of the passenger compartment is particularly preferably formed with the profile strip.
  • the available space at the passenger compartment can be optimally utilized by the Pultrusionsbauteii the entire height of the shell component is designed to cover.
  • Fig. 2 shows a cross section of a first embodiment of a profile strip a
  • FIG. 3 is a sectional perspective view of the profiled strip according to FIG. 2, FIG.
  • Fig. 4 shows a cross section of a second embodiment of a profile strip a
  • a profile strip 10 is shown in the form of a sill of a passenger compartment of a vehicle body, which is formed from a total of four differently curved, elongate shell components 12 made of fiber-reinforced plastic.
  • the shell components 12 are each made of synthetic resin with associated fiber inserts as flat elements or shells. They are substantially U-shaped respectively L-shaped curved in such a way that with them a total of two juxtaposed, closed hollow sections, one with respect to FIG. 1 right, first hollow section 14 and a left next to it, second hollow section 16 is formed are.
